This is so wonderful. If this is from the late 70's, I was living in Arizona at the time and the PBS station in Phoenix (KAET-9) never carried this show. But I enjoyed watching the youtube clips of "Once Upon A Time".
I've tried to explain in another forum how the rise of Sesame Street spelled the death of all the other children's programming. The generation who, like me, remembers what PBS was like when local stations produced their own kids shows is growing old. Now I meet people who only know Big Bird, and that's a shame.
The woman who played Marion the Librarian has a daughter, and she has posted a tribute to her mom on youtube:
